Experimental Investigation of Two Test Setups on Straw Bales Used as Load-Bearing Elements of Buildings

The importance of green and sustainable materials in civil engineering is undeniable. Alongside modern practices that improve the properties of standard building materials, there are ways to revive forgotten techniques, including straw bale buildings. Straw bales are load-bearing structures, which a...
